Bone and joint infections (BJI) are rare serious pathology which can lead to a very heavy handicap and sometimes to the life threatening. These are devastating diseases whose diagnosis is difficult. They are known to be associated with high mortality rates (5%) and significant morbidities responsible for functional sequelae (40% of patients) with an individual cost (prolonged hospitalization, altered quality of life) and societal (work stoppage, partial or total disability, temporary or permanent) extremely high.

These bone and joint infections have a significant impact on the quality of life of those affected who, in addition to their infection, are reduced in their autonomy and often need to be taken care of outside their home, sometimes away from home.

To the knowledge of investigators, there are few studies on the measurement of quality of life in patients with osteoarticular infection.

The aim of this study is to implement the EQ-5D-3L validated quality of life questionnaire and the EVA scale (created by EuroQol Group) for each patient with a prosthetic joint infection (IPA) on prosthesis during their medical care in the department of Infectious and Tropical Diseases.

Inclusion Criteria:

• Patient having prosthetic joint infection
• Patient who did not object to participate in the study
• Patients over 18 years of age

Exclusion Criteria:

• Patient with additional psychological or psychiatric support outside the service.
• Patient benefiting from a system of legal protection (safeguard of justice, guardianship, curatorship)
• Patient participating in another study on measuring quality of life
• Patients with cognitive impairment to understand the questionnaire
• Impossibility of giving the patient informed information
• Patients with no infection diseases follow up at the CROIX ROUSSE hospital
• Patients with amputation as initial surgery for infection management
